We took the Radeon x800 Pro and Radeon x800 XT, GeForce 6800 GT and GeForce 6800 Ultra and started measuring performance on that Pentium 4 2.8 GHz system and then did the exact same thing on the Athlon 64 3800+. Now before we beging I need to make clear that you need to see things in relation to the processor. A faster CPU obviously means a newer platform thus a newer mainboard and memory utilisation also. Primary the advantage will come from the CPU though
